Something one needs to mess around with to get to work properly, each time, is futtzy. Something not precisely simple or un-complex, something not plug-n-play, is futtzy. Something requiring multiple steps completed in specific order and requiring a large chunk of ones attention, usually diverted from another concurrent task, for proper operation, is futtzy.

I love my new phone with navigation, I just type in an address and it voice prompts me over my car audio system, interrupting my streaming music as needed so it aint futtzy at all!
